Journal ArticleDOI
Genome and transcriptome sequencing of lung cancers reveal diverse mutational and splicing events
Jinfeng Liu,William Lee,Zhaoshi Jiang,Zhongqiang Chen,Suchit Jhunjhunwala,Peter M. Haverty,Florian Gnad,Yinghui Guan,Houston Gilbert,Jeremy Stinson,Christiaan Klijn,Joseph Guillory,Deepali Bhatt,Steffan Vartanian,Kimberly Walter,Jocelyn Chan,Thomas Holcomb,Peter Dijkgraaf,Stephanie Johnson,Julie Koeman,John D. Minna,Adi F. Gazdar,Howard M. Stern,Klaus P. Hoeflich,Thomas D. Wu,Jeff Settleman,Frederic J. de Sauvage,Robert Gentleman,Richard M. Neve,David Stokoe,Zora Modrusan,Somasekar Seshagiri,David S. Shames,Zemin Zhang +33 more
TL;DR: Deep whole-genome sequencing and transcriptome sequencing on 19 lung cancer cell lines and three lung tumor/normal pairs show that cell line models exhibit similar mutation spectra to human tumor samples, and demonstrate that cancer-specific alternative splicing is a widespread phenomenon that has potential utility as therapeutic biomarkers.
Journal ArticleDOI
Application of mass spectrometry profiling to establish brusatol as an inhibitor of global protein synthesis
Steffan Vartanian,Taylur P. Ma,James Lee,Peter M. Haverty,Donald S. Kirkpatrick,Kebing Yu,David Stokoe +6 more
TL;DR: The data show that the activity of brusatol is not restricted to Nrf2 but, rather, functions as a global protein synthesis inhibitor and induces its potent cellular cytotoxicity effects on multiple cancer cell lines in a manner independent of KEAP1/Nrf2 activity and with a profile similar to the protein translation inhibitor silvestrol.
Journal ArticleDOI
Identification of mutant K-Ras-dependent phenotypes using a panel of isogenic cell lines.
Steffan Vartanian,Carolyn Bentley,Matthew J. Brauer,Li Li,Senji Shirasawa,Takehiko Sasazuki,Jung-Sik Kim,Pete Haverty,Eric Stawiski,Zora Modrusan,Todd Waldman,David Stokoe +11 more
TL;DR: It is concluded that there are conserved components of mutant K-Ras signaling and phenotypes but that many depend on cell context and environmental cues.
Journal ArticleDOI
A requirement for wild-type Ras isoforms in mutant KRas-driven signalling and transformation.
Carolyn Bentley,Stefanie S. Jurinka,Noelyn M. Kljavin,Steffan Vartanian,Sree R. Ramani,Lino C. Gonzalez,Kebing Yu,Zora Modrusan,Pan Du,Richard Bourgon,Richard M. Neve,David Stokoe +11 more
TL;DR: It is demonstrated that the WT copies of HRas, NRas and KRas play unique roles in the context of mutant KRas-driven tumours.
Journal Article
Testisin, a glycosyl-phosphatidylinositol-linked serine protease, promotes malignant transformation in vitro and in vivo.
TL;DR: The functional data coupled with the restricted normal tissue distribution of testisin and its overexpression in a majority of ovarian cancers validates this cell surface protein as a target for therapeutic intervention.
